Help me please I dont know what to do
gtnhenbr [62]

Answer:

It's <u>option A. ± </u>√6<u>0</u>

Step-by-step explanation:

x^2  = 60

here ^2 will move to the other side and when it does it'll become a square root to 60.

so, x = √60

now, the answer in its simplified form would be 2√15 and -2√15.

The answer of this square root will be negative as well as positive, so, ±√60.
